Wireless communication, radar, electronic countermeasures, and other systems are continuously evolving toward higher power and higher integration. However, mainstream passive device technology routes generally face the problem that "power and integration cannot be achieved simultaneously": GaAs IPD can achieve chip-scale size, but its power handling capability is essentially limited to the 0.5 W to 10W range; cavity and waveguide solutions deliver both performance and power, but their large size makes it difficult to meet miniaturization requirements; LTCC offers a compromise between medium power and relatively small size, yet sacrifices integration or frequency coverage. None of the three approaches can simultaneously satisfy power handling, size, and integration.
Bonray addresses this problem based on its GaN IPD high-power platform. Within the same chip footprint as GaAs IPD, it extends power handling capability to over 100W, achieving high power and chip-scale integration simultaneously, effectively improving the system integration level for radar, communication, and other applications.
Core Technology and Process Advantages
The new high-power IPD passive product series is based on the GaN IPD process, covering DC to 40GHz, and includes six major categories: fixed attenuators, filters, couplers, power dividers, power loads, and equalizers. Power levels range from 10W to 100W, with both bare die and plastic package delivery options available. The series is widely applicable in systems with stringent requirements for miniaturization, high integration, and high power, such as radar, electronic countermeasures, and communications.
Performance Comparison with Typical GaAs IPD Products
From an overall comparison, under similar size scales, fixed attenuators, filters, power dividers, couplers, and power loads all significantly outperform GaAs IPD solutions in terms of power handling capability, while other key specifications are generally better than or comparable to industry peers.
New Product Series Introduction
Product Series Summary Table
Attenuator Series New Products
The attenuator series new products cover DC to 40GHz, with attenuation values available in multiple steps from 1dB to 20dB. Attenuation flatness is ±0.3dB across the full frequency band, and power handling is up to 20W.
Filter Series New Products
The filter series new products include high‑pass and band‑pass filters, covering a frequency range of 0.8GHz to 30GHz. Among them, the 2GHz to 4GHz band‑pass filter offers an insertion loss as low as 1.3dB at the center frequency, with out‑of‑band rejection better than 30dBc, effectively suppressing out‑of‑band spurs and harmonics to ensure signal purity. The product handles up to 10W of power, making it suitable for system applications with combined requirements for power and signal quality.
Coupler Series New Products
The coupler series new products cover multiple frequency bands from 0.8GHz to 20GHz, with coupling values of 15, 20, or 25dB, insertion loss ≤0.4dB, and power levels of 50W or 100W, enabling precise sampling and monitoring of high‑power signals.
Power Divider Series New Products
The power divider series new products cover multiple frequency bands from DC to 18GHz, with typical insertion loss of 0.5dB and power levels of 30W or 40W, enabling efficient equal splitting and distribution of high‑power signals.
